Radiographic image capturing apparatus, radiographic image capturing system, and method of supplying electric power to radiographic image capturing apparatus

A portable radiographic image capturing apparatus comprising:

• a radiation source device including:
• an electric power storage unit;
• and
• a radiation source for outputting radiation;
• and
• a detector device including:
• an electric power storage unit;
• and
• a radiation detector for detecting radiation that is transmitted through a subject when the subject is irradiated with radiation by the radiation source, and converting the detected radiation into a radiographic image,
• wherein at least one of the radiation source device and the detector device has an electric power supply limiting unit for limiting supply of electric power,
• the electric power supply limiting unit including:
• an electric power controller that controls supply of electric power between the electric power storage unit of the radiation source device and the electric power storage unit of the detector device;
• and
• an electric power supply limiter that limits supply of electric power between the electric power storage unit of the radiation source device and the electric power storage unit of the detector device, depending on timing of an image capturing process,
• wherein the electric power controller of the electric power supply limiting unit supplies electric power only along a route from the electric power storage unit of the detector device to the electric power storage unit of the radiation source device, upon completion of the image capturing process.
